Bending machine for steel structure metal pipe fitting

Abstract

The invention relates to a bending machine for a steel structure metal pipe fitting. The bending machine comprises a supporting frame, a bending device and a clamping device, the supporting frame is of a U-shaped structure, the bending device is installed above the supporting frame, the clamping device is arranged below the bending device, and the clamping device is installed on the supporting frame. The bending machine for the steel structure metal pipe fitting can solve the problem that when an existing bending machine for a metal pipe fitting bends the metal pipe fitting, graded extrusion bending of the metal pipe fitting cannot be achieved, so that a straight pipe poor in bendability is prone to cracking and even the problem of breaking occurs during bending, the qualified rate of a finished bent pipe is affected, and the problem that when the existing bending machine clamps and fixes the metal pipe fitting, the clamping mechanism cannot be correspondingly adjusted along with position change of pipe fitting deformation, damage to a formed bent pipe is caused, the quality of the formed bent pipe is affected, metal pipe fittings with different diameters cannot be clamped and fixed, the formed bent pipe is unique in shape and single in diameter, and the use range is limited are solved.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, in particular to a bending machine for steel structure metal pipe fittings. Background technique [0002] Steel structure building is a relatively common way in the field of construction at present. Steel structure buildings are more popular in bridges, houses and factories. Steel structure buildings need to use elbows for connection at special positions during the construction process. Steel structure buildings The processing quality of the bent pipe directly affects the overall quality of the steel structure building, so the processing of the steel structure bent pipe is also crucial to the overall building. [0003] At present, there are the following defects for the existing steel structure metal pipe fitting bending machine: 1. When the existing steel structure metal pipe fitting bending machine bends the metal pipe fitting, most of them use one-time extrusion to make the ...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that most of the existing steel structure metal pipe fitting bending machines use one-time extrusion to make the metal pipe fittings be squeezed and deformed when bending the metal pipe fittings, and cannot adjust and replace the bending head, and cannot realize graded extrusion Bending, the straight pipe with poor bendability is easy to crack or even break when bending, which affects the pass rate of the finished pipe. It can also solve the problem of the existing steel structure metal pipe fitting bending machine on the metal When the pipe fittings are clamped and fixed, the clamping mechanism cannot make a corresponding arc movement with the deformation of the metal pipe fittings, which will cause extrusion damage to the formed elbow and affect the quality of the formed elbow. It is inconvenient to release the clamp after bending and forming. The degree of automation is low, labor is wasted, and metal pipe fittings of different diameters cannot be clamped and fixed, resulting in the problem that the shape of the bent pipe is formed, the diameter is single, and the scope of use is limited.
